Drawer of computer desk

ABSTRACT

An improved drawer of the computer desk allows assembling of a combined drawer unit underneath the computer desk. The drawer unit consists of a mother drawer, a subdrawer and several guideway assemblies. Both sides of the mother drawer are assembled via a guideway assembly onto the computer desk. The subdrawer is assembled at inner edge of the mother drawer. The guideway assembly is separately set between two external sides and an inner side corresponding to the mother drawer. The mother drawer and subdrawer can form a combined sleeving structure to save space and increase use convenience.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a computer desk, and moreparticularly to an innovative one which is designed specifically with adrawer.

2. Description of Related Art

As illustrated in Taiwan Patent No. 86215737 a dual-layer drawerstructure of computer desk is shown. Such a mechanical structuregenerally comprises a desktop, laminate panel, left/right brackets atthe bottom of the desktop, upper/lower side guides incorporatedseparately onto the brackets; the upper side guides at both sides allowfor mating and displacement of the upper drawer via guideway or pulley,whilst the lower side guides at both sides allow for mating anddisplacement of the lower drawer, thus realizing a structure ofdual-layer drawer. Yet, as the upper/lower drawer is fitted separatelywith a keyboard and a holding space, and also installed independentlywith two guideways arranged vertically side by side, this complexstructure makes it difficult for space-saving and convenient use.

Thus, to overcome the aforementioned problems of the prior art, it wouldbe an advancement in the art to provide an improved structure that cansignificantly improve the efficacy.

Therefore, the inventor has provided the present invention ofpracticability after deliberate design and evaluation based on years ofexperience in the production, development and design of relatedproducts.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide an improveddrawer of computer desk which comprises a computer desk and a drawerunit assembled underneath the desktop of the computer desk, etc. Twoparallel slide bars are arranged horizontally underneath the desktop ofthe computer desk, and also sleeved onto the upper end of two connectingplates; the other end of these two connecting plates is connected to thedrawer unit. The drawer unit consists of a mother drawer, subdrawer andseveral guideway assemblies; the mother drawer is of an inverted Upattern, both sides of which are assembled via a guideway assembly ontoa plate correspondingly to these two connecting plates; the subdrawer isassembled at inner edge of the mother drawer, and a guideway assembly isseparately set between two external sides and an inner sidecorresponding to the mother drawer. Moreover, the guideway assemblyconsists of sliding seats and guideways, of which two first slidingseats are secured onto a plate correspondingly to these two connectingplates; two first guideways are secured onto the external surface of themother drawer corresponding to the connecting plate; next, two secondsliding seats are set at inner side of the mother drawer, while twosecond guideways are secured separately onto external surface of thesubdrawer; with such a combined design, the compact and delicatestructure of drawer unit enables to reduce the assemblies and footprintof the computer desk, thus minimizing the cost and improving theassembly efficiency; meanwhile, the drawer can be pulled or drawn moreeasily, or adjusted more conveniently by the users along two slide bars.

The features, structure and advantages of the present invention will bemore readily understood upon a thoughtful deliberation of the followingdetailed description of a preferred embodiment of the present inventionwith reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1-7, an improved drawer of computer desk of thepresent invention comprises a computer desk 10 and a drawer unit 20assembled underneath the computer desk 10.

The computer desk 10 generally permits to arrange a desktop 11horizontally on the upper flange of a desk framework, and two parallelslide bars 12 transversely at proper location below the desktop 11, aswell as two connecting plates 13; these two connecting plates 13 areprovided separately with a slide bushing 14 at both ends of the upperflange, then two slide bars 12 are sleeved with the slide bushing 14, sothese two connecting plates 13 are mated with these two slide bars 12slideably.

The drawer unit 20 consists of a mother drawer 21, subdrawer 22 andseveral guideway assemblies 23. The mother drawer 21 of an inverted Upattern is provided with a holding space to accommodate the subdrawer22; both sides of the mother drawer 21 are assembled via a guidewayassembly onto a plate correspondingly to these two connecting plates 13.The subdrawer 22 is a common drawer structure; when it is assembled atinner edge of the mother drawer 21, a guideway assembly 23 is separatelyset between two external sides and an inner side corresponding to themother drawer 21. The mother drawer 21 and subdrawer 22 can slideseparately to form a combined sleeving structure.

Secondly, the guideway assembly 23 consists of a sliding seat andguideway; two first sliding seats 231 are secured onto a platecorrespondingly to these two connecting plates 13; two first guideways232 are secured onto the external surface of the mother drawer 21corresponding to the connecting plate 13. Meanwhile, two second slidingseats 231′ are set at inner side of the mother drawer 21, while twosecond guideways 232′ are secured separately onto external surface ofthe subdrawer 22; the mother drawer 21 and subdrawer 22 can slideseparately.

With the aforementioned structural design that the mother drawer 21 andsubdrawer 22 form a combined sleeving structure, and the drawer unit 20can slide along two slide bars 12 via two connecting plates 13, theusers can slide it transversely to a proper position; hence, the compactand delicate structure of drawer unit 20 enables to reduce theassemblies and footprint of the computer desk, thus minimizing the costand improving the assembly efficiency; meanwhile, the drawer can bepulled or drawn more easily, or the drawer unit 20 can be adjusted moreconveniently by the users.

Additionally, when the present invention is operated, the drawer unit 20can be slideably set underneath the computer desk 10, so the operatingspace of the desktop 10 can be increased, enabling the users to placethe keyboard onto the mother drawer 21, and put articles such asstationery or pencils into the subdrawer 22 with improved applicability.

While the invention has been described in terms of preferredembodiments, those skilled in the art will recognize that the inventioncan be practiced with modifications within the spirit and scope of theappended claims.
